[0002] Scour refers to the friction and impact of water flow on the surface slope on the surface material, as well as the friction and impact of particles that are knocked off the surface by the water flow on the surface, causing the surface material to move and be transported down the slope. Therefore, it is necessary to conduct a scour test on the road material. The road material (such as cement concrete) is placed in the scour test device, and then the scour test is conducted. The surface defects caused by water scouring the cement concrete surface are inspected. The scour test device consists of a box, universal wheels, a transparent window, a water pipe one, a water pump, a water pipe two, a water accumulation tray, a scour nozzle, a connecting rod, a scour table and a piston. When conducting a scour test on the cement concrete block, open the transparent window, place the cement concrete block on the scour table, and inject water into the bottom of the box. Be careful not to overflow the transparent window.
